Deepest Chesapeake Bay Channels |
A request was made in October 2006 for a map delineating the deepest parts of the
Chesapeake Bay. These deep areas can be thought of as relict thalwegs
of modern and ancient rivers in the Chesapeake Bay watershed. Please
note this GIS data contains only the channel traces, not the shoreline or shaded
bathymetry shown in the thumbnail image on this page.
METADATA SUMMARY
| Description: Polyline map tracing the deepest
parts of the Chesapeake Bay and its tidal estuaries. Channels were
digitized based on deepest contours, channel slope, channel width and
bottom geomorphology. Contour data derived from NOAA/NOS 30 meter gridded
DEM for Chesapeake Bay bathymetry |
| Purpose: The
deepest parts of the Bay and its estuaries may represent a natural
barrier to cross-channel sediment transport. This map was developed
as a starting point to assist in modeling sediment transport in the
Bay. |
